This Keyboard Polling Rate Test lets you check how often your keyboard sends key input data to your computer. The polling rate is measured in Hertz (Hz). A higher rate means faster input updates and lower delay. This tool works directly in your browser and requires no setup or downloads.
Top 5 Mechanical Gaming Keyboards Built For Comfort And Speed
What Is Keyboard Polling Rate (Hz)?
Keyboard polling rate is how many times per second your keyboard reports keypress data to your computer. This value is measured in Hertz (Hz).
For example, a keyboard running at 1000 Hz sends key input updates 1000 times every second. Higher polling rates reduce the delay between pressing a key and the system registering it, which can improve responsiveness during typing and gaming.
How Keyboard Polling Works
Keyboards send key state updates to the computer at fixed time intervals through a USB or wireless connection. The polling rate determines how often these updates are sent.
Shorter intervals mean faster communication between the keyboard and the system, which results in lower input delay.
Common Keyboard Polling Rates
125 Hz (8 ms): Standard office keyboards and basic typing
250 Hz (4 ms): Casual use and general productivity
500 Hz (2 ms): Casual gaming and faster typing
1000 Hz (1 ms): Gaming keyboards and competitive play
8000 Hz (0.125 ms): Ultra-high-end keyboards with strong system requirements
Polling Rate vs Scan Rate — What’s the Difference?
Many users confuse polling rate with scan rate. These are two separate systems that work together to determine your total keyboard latency.
Scan rate measures how often your keyboard’s internal microcontroller checks its key matrix for new presses. This happens inside the keyboard before any data gets sent to your computer. A keyboard with 1000Hz scan rate checks its keys 1,000 times per second.
Polling rate measures how often your keyboard sends that data to your computer through USB. Even if your keyboard scans at 8000Hz internally, if your USB polling rate is set to 1000Hz, your computer only receives updates 1,000 times per second.
Think of it this way:
- Scan rate = How often the keyboard looks for key presses
- Polling rate = How often the keyboard reports what it found
Both matter. A keyboard with an 8000Hz scan rate but a 125Hz polling rate will still feel slow because the computer only gets updates every 8ms. A keyboard with a 125Hz scan rate but a 1000Hz polling rate cannot send fresh data every 1ms because it only checks for new presses every 8ms.
Quality gaming keyboards optimize both scan rate and polling rate. Most modern mechanical keyboards run a 1000Hz scan rate with a 1000Hz polling rate, creating a balanced 1ms total internal latency before USB transfer.
Understanding Total Keyboard Latency (The Complete Formula)
Your keyboard’s total latency comes from multiple stages working together. Understanding this formula helps you identify where delays actually occur.
The Complete Latency Formula
Total Keyboard Latency = Debounce Time + Scan Rate Delay + Polling Rate Delay + USB Transfer Time + System Processing
Let’s break down each component with real numbers:
| Stage | Typical Time | What Happens |
|---|---|---|
| Debounce Time | 5-10 ms | Switch contacts stabilize after press, firmware filters bounce |
| Scan Rate Delay | 0.125-8 ms | Keyboard checks key matrix and detects the press |
| Polling Rate Delay | 0.125-8 ms | Keyboard waits for next USB polling cycle to report |
| USB Transfer Time | 0.1-0.5 ms | Data travels through USB cable to computer |
| System Processing | 1-5 ms | OS receives and processes the keystroke |
Example: Standard Gaming Keyboard
- Debounce: 5 ms
- Scan rate (1000Hz): 1 ms
- Polling rate (1000Hz): 1 ms
- USB transfer: 0.5 ms
- System processing: 3 ms
Total latency: 10.5 ms
This explains why even a perfect 8000Hz polling rate (0.125ms) cannot eliminate all input lag. The other stages contribute 9-10ms of delay that polling rate cannot fix.
What This Means for You
If your keyboard feels slow, check all stages:
- Update firmware (reduces debounce time)
- Verify scan rate in manufacturer software
- Test polling rate with this tool
- Use USB 3.0 ports (faster transfer)
- Close background apps (reduces system processing)
Focusing only on the polling rate while ignoring the other four stages delivers minimal improvement.
Why Keyboard Polling Rate Matters
A higher keyboard polling rate reduces the delay between pressing a key and seeing the action on screen. This makes input feel faster and more consistent.
For everyday typing, moderate polling rates are usually enough. For gaming or fast input tasks, higher polling rates can improve precision and timing.
How to Use the Keyboard Polling Rate Test
- Reset the test and repeat if needed to confirm stability.
- Open the keyboard polling rate test in your browser.
- Make sure this tab is active.
- Press and hold any key or tap it repeatedly for several seconds.
- Watch the polling rate (Hz) update in real time.
Fixing Low or Unstable Keyboard Polling Rate
If your keyboard reports a lower or unstable polling rate:
- Try a different USB port on the motherboard
- Avoid USB hubs and front-panel ports
- Disable USB power-saving options
- Update or reinstall keyboard drivers
- Switch from Bluetooth to a wired or 2.4 GHz connection
After each change, retest the polling rate to confirm improvement.
How to Optimize Windows for High Polling Rates
Windows power management and USB settings can artificially limit your keyboard’s polling rate. Optimizing these settings ensures your system actually delivers the performance your hardware supports.
Step 1: Enable Ultimate Performance Power Plan
Windows hides its highest-performance power plan by default. Enabling it prevents the system from throttling USB devices to save power.
How to enable Ultimate Performance:
- Open Command Prompt as Administrator
- Type:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 - Press Enter
- Open Control Panel → Hardware and Sound → Power Options
- Select “Ultimate Performance”
This plan disables all power-saving features that could interfere with keyboard polling.
Step 2: Disable USB Selective Suspend
USB Selective Suspend allows Windows to power down USB devices to save energy. This creates inconsistent polling rates as devices wake and sleep.
How to disable it:
- Control Panel → Power Options
- Click “Change plan settings” next to your active plan
- Click “Change advanced power settings.”
- Expand “USB settings” → “USB selective suspend setting.”
- Set to “Disabled” for both “On battery” and “Plugged in.”
- Click Apply
Step 3: Update USB Drivers
Outdated USB chipset drivers cause polling rate instability and artificial caps.
How to update:
- Press Win + X → Device Manager
- Expand “Universal Serial Bus controller.”
- Right-click your USB Root Hub → Update driver
- Choose “Search automatically for drivers.”
- Repeat for all USB Root Hub entries
- Restart your computer
For best results, download USB drivers directly from your motherboard manufacturer’s website rather than relying on Windows Update.
Step 4: Set High-Performance USB Settings
Windows defaults to power efficiency over performance. Changing USB power delivery improves polling consistency.
Registry setting (advanced users only):
- Press Win + R → type
regedit→ Enter - Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags - If a value named
DisableSelectiveSuspenddoes not exist, create it (DWORD, 32-bit) - Set value to 1
- Restart
Warning: Only edit the registry if you are comfortable with advanced system settings. Incorrect changes can cause system instability.
Step 5: Test in Safe Mode (Troubleshooting)
If optimizations do not fix low polling rates, test in Safe Mode to rule out software interference.
How to boot Safe Mode:
- Settings → Update & Security → Recovery
- Under “Advanced startup,” click “Restart now”
- Choose Troubleshoot → Advanced options → Startup Settings → Restart
- Press 4 for “Enable Safe Mode”
Run your keyboard polling test in Safe Mode. If the polling rate jumps to expected levels, a background application or driver is interfering. Common culprits include RGB control software, game overlays, and antivirus programs.
Wireless Keyboards — 2.4GHz vs Bluetooth Explained
Wireless keyboards use two different wireless technologies, and the one your keyboard uses determines its maximum possible polling rate.
2.4GHz Wireless (Proprietary Dongles)
Gaming wireless keyboards use proprietary 2.4GHz wireless protocols with dedicated USB dongles. Examples include Logitech Lightspeed, Razer HyperSpeed, and Corsair Slipstream.
Maximum polling rate: 1000Hz
These connections match wired performance at 1000Hz with only 1-2ms of added latency. The wireless protocol dedicates the entire 2.4GHz channel to keyboard communication with minimal interference.
Advantages:
- Supports up to 1000Hz polling reliably
- Low latency (1-3ms added overhead)
- Stable connection with minimal interference
- Works identically to wired for competitive gaming
Disadvantages:
- Requires USB dongle (takes up a port)
- Cannot exceed 1000Hz (wireless bandwidth limitation)
- Higher battery drain at 1000Hz (1-2 weeks per charge)
Bluetooth Wireless
Bluetooth keyboards use the universal Bluetooth protocol designed for power efficiency across many device types.
Maximum polling rate: 125-250Hz
Bluetooth prioritizes battery life over speed. The protocol compresses data and introduces buffering that makes high polling rates impossible.
Advantages:
- Works with any Bluetooth-enabled device (no dongle needed)
- Exceptional battery life (3-6 months per charge)
- Universal compatibility
Disadvantages:
- Caps at 125Hz polling rate (8ms delay)
- An additional 5-15ms connection latency
- Variable performance based on interference
- Unsuitable for competitive gaming
Polling Rate Comparison
| Connection Type | Max Polling Rate | Added Latency | Battery Life | Gaming Suitable? |
|---|---|---|---|---|
| Wired USB | 8000Hz | 0 ms | N/A | ✅ Yes |
| 2.4GHz Wireless | 1000Hz | 1-3 ms | 1-2 weeks | ✅ Yes |
| Bluetooth | 125-250Hz | 5-15 ms | 3-6 months | ❌ No |
Battery Life vs Polling Rate Trade-Off
Even 2.4GHz wireless keyboards let you adjust the polling rate to extend battery life:
- 1000Hz: 1-2 weeks per charge, competitive performance
- 500Hz: 2-4 weeks per charge, still excellent for gaming
- 125Hz: 2-3 months per charge, fine for typing and casual use
Most wireless gaming keyboards include software profiles that automatically lower the polling rate when idle and raise it when gaming starts.
Why Browser Tests Show Lower Hz Than Expected
If your keyboard is set to 1000Hz but this test shows 700-900Hz, you are not alone. This is completely normal and does not mean your keyboard is broken.
Why Browser Tests Read Lower
JavaScript-based browser tests cannot access raw USB data. Instead, they measure keyboard events processed through multiple software layers:
What happens when you press a key:
- Keyboard sends USB data at true polling rate (1000Hz)
- USB driver receives and queues the data
- The operating system processes the queue
- The browser receives the processed event through its API
- JavaScript timing functions measure the interval
Each layer adds small delays and timing imprecision. By the time JavaScript measures the interval, 10-20% of the original polling rate precision has been lost to browser overhead.
What’s Actually Normal
| Keyboard Setting | Browser Test Result | Status |
|---|---|---|
| 1000 Hz | 700-950 Hz | ✅ Normal browser overhead |
| 1000 Hz | 950-1050 Hz | ✅ Excellent, minimal overhead |
| 1000 Hz | 400-600 Hz | ⚠️ Possible USB issue or interference |
| 1000 Hz | Under 400 Hz | ❌ Hardware or driver problem |
When to Actually Worry
Your keyboard has a real problem if:
- Browser test shows under 400Hz when set to 1000Hz
- Results fluctuate wildly (200Hz one second, 800Hz the next)
- Native software (Logitech G HUB, Razer Synapse) also shows low rates
- Different USB ports all show identical low results
Getting More Accurate Results
For the most accurate browser-based testing:
- Close all other browser tabs
- Close background applications
- Use a direct rear USB port (not a hub)
- Press keys at a steady, consistent rhythm
- Run the test for at least 10 seconds
- Take the average of 3 separate tests
Browser tests are perfect for relative comparisons. If Keyboard A shows 850Hz and Keyboard B shows 450Hz, Keyboard A genuinely polls faster — even if neither number is perfectly precise.
Typical Polling Rate Values by Keyboard Type
These are the polling rate values you will commonly see when using a keyboard frequency test or test keyboard Hz tool:
| Type | Polling Rate | Average Delay |
|---|---|---|
| Standard Office Keyboard | 125 Hz | 8 ms |
| Mid-Range Mechanical | 500 Hz | 2 ms |
| Gaming Keyboard | 1000 Hz | 1 ms |
You can confirm each of these values through a quick keyboard polling test to see if your device matches its advertised performance.
Top Keyboards by Polling Rate (Hz Ranking)
| Model | Type | Polling Rate | Ideal Use |
|---|---|---|---|
| Logitech G915 | Wireless | 1000 Hz | Competitive gaming |
| Razer Huntsman V2 | Wired | 8000 Hz (adaptive) | Professional esports |
| Corsair K70 RGB TKL | Wired | 1000 Hz | FPS and MMO players |
| Keychron K6 | Bluetooth | 125–250 Hz | Casual gaming |
8000Hz Keyboards — Marketing Hype or Real Performance?
Keyboard manufacturers aggressively market 8000Hz polling rates as “8x faster than competitors” or “instant zero-delay input.” The reality is far more nuanced.
The Honest Truth About 8000Hz
What you actually gain: Upgrading from 1000Hz to 8000Hz reduces polling delay by 0.875ms (from 1ms to 0.125ms).
What you do NOT gain: Elimination of input lag. Your keyboard’s total latency includes debounce time (5ms), scan rate delay (1ms), and system processing (3ms). Even with perfect 8000Hz polling, total latency still sits around 9ms. You saved less than 1ms out of 10ms total.
When 8000Hz Actually Helps
8000Hz provides measurable benefits in exactly three scenarios:
1. You own a 360Hz+ monitor. At 360Hz, each frame lasts 2.8ms. An 8000Hz keyboard (0.125ms polling) catches every single frame cycle. A 1000Hz keyboard (1ms polling) might occasionally miss a frame by microseconds.
2. You play rhythm games like OSU. These games require frame-perfect timing, where even 0.5ms differences affect scoring. 8000Hz helps competitive rhythm gamers — not FPS players.
3. You already eliminated every other source of lag. If you run a top-tier CPU, 240Hz+ monitor, wired low-latency mouse, and optimized network, then 8000Hz keyboards provide the final 0.875ms of improvement. For everyone else, dozens of larger delays exist elsewhere in your system.
When 8000Hz Actually Hurts
- CPU overhead increases significantly. Your processor handles eight times more keyboard interrupts per second. On mid-tier systems or while streaming, this extra load causes frame drops that hurt performance more than the 0.875ms polling improvement helps.
- USB 3.0 required. USB 2.0 ports physically cannot support 8000Hz. If you plug an 8000Hz keyboard into a USB 2.0, it automatically caps at 1000Hz. Many motherboards only have 1-2 USB 3.0 ports, forcing trade-offs between keyboard, mouse, and other peripherals.
- Most games cannot utilize it. Valorant processes input at 128 ticks (7.8ms per update). CS2 runs 64 ticks with subtick interpolation. Your 8000Hz keyboard sends updates every 0.125ms, but the game only reads input every 7-16ms. Most of those ultra-fast updates get discarded unused.
Keyboard Polling Rate by Game — What You Actually Need
Different games have different input requirements. Here is what the polling rate actually matters for each major competitive title.
Valorant
Recommended: 1000Hz
Valorant runs at a 128 tick rate (7.8ms per server update). Your keyboard polling at 1000Hz sends updates every 1ms — fast enough to catch every server tick with room to spare. Going beyond 1000Hz provides zero benefit because the game server processes input slower than your keyboard reports it.
Professional Valorant players universally use 1000Hz keyboards. None use 8000Hz despite having access to unlimited budgets. Reliability and consistency matter more than theoretical spec advantages.
CS2 (Counter-Strike 2)
Recommended: 1000Hz
CS2 uses Valve’s subtick system, which interpolates between 64Hz server ticks. Higher polling rates could theoretically improve subtick accuracy, but network latency (15-50ms) completely dominates any sub-millisecond polling gains.
Top CS2 pros stick with 1000Hz. The jump to 8000Hz is imperceptible compared to other factors like internet connection quality and monitor refresh rate.
Fortnite
Recommended: 1000Hz
Fortnite’s build mechanics create rapid input sequences, but the game runs on 30 tick servers (33ms between updates). Your keyboard’s polling rate has virtually zero impact on building speed — the server tick rate is the limiting factor.
What actually matters for Fortnite: Switch actuation speed and key consistency. A keyboard with fast mechanical switches at 1000Hz outperforms a slow membrane board at 8000Hz every time.
Apex Legends
Recommended: 1000Hz
Apex runs 60 tick servers (16.6ms per update). Your 1000Hz keyboard reports every 1ms, giving the server 16 fresh updates per tick cycle. Going higher wastes CPU cycles processing reports that the server discards.
Movement tech in Apex (tap-strafing, super-glides, wall-bounces) depends on timing consistency rather than raw polling speed. A stable 1000Hz connection beats an unstable 8000Hz connection every time.
OSU and Rhythm Games
Recommended: 1000-2000Hz minimum, higher beneficial
OSU is the one competitive game where ultra-high polling rates provide measurable advantages. The game requires frame-perfect inputs where 0.125ms differences actually affect scoring accuracy.
Top OSU players often use 2000Hz or 4000Hz keyboards. Some use 8000Hz. However, even in OSU, timing consistency matters more than raw polling rate. A perfectly-tuned 1000Hz board with zero jitter outperforms an inconsistent 8000Hz board.
League of Legends / Dota 2
Recommended: 500-1000Hz
MOBAs process input at slower tick rates and gameplay revolves around strategic decisions rather than split-second reflexes. 500Hz delivers perfectly adequate performance. 1000Hz provides a slight edge for ability combos and animation canceling.
Summary Table
| Game | Server Tick Rate | Recommended Polling Rate | Does 8000Hz Help? |
|---|---|---|---|
| Valorant | 128 tick | 1000Hz | ❌ No benefit |
| CS2 | 64 tick (subtick) | 1000Hz | ❌ Negligible |
| Fortnite | 30 tick | 1000Hz | ❌ No benefit |
| Apex Legends | 60 tick | 1000Hz | ❌ No benefit |
| OSU / Rhythm | Frame-perfect | 1000-4000Hz | ✅ Yes, helps scoring |
| LoL / Dota 2 | 30-60 tick | 500-1000Hz | ❌ No benefit |
USB 3.0 vs USB 2.0 — Why It Matters for High Polling Rates
Your USB port version determines the maximum polling rate your keyboard can achieve. Plugging an 8000Hz keyboard into the wrong port caps performance regardless of what your software settings say.
USB Standard Limitations
| USB Standard | Maximum Polling Rate | Bandwidth | Year Released |
|---|---|---|---|
| USB 2.0 | 1000Hz | 480 Mbps | 2000 |
| USB 3.0 (3.1 Gen 1) | 8000Hz+ | 5 Gbps | 2008 |
| USB 3.1 (3.1 Gen 2) | 8000Hz+ | 10 Gbps | 2013 |
| USB 3.2 | 8000Hz+ | 20 Gbps | 2017 |
USB 2.0 physically cannot support polling rates above 1000Hz. The USB 2.0 specification limits keyboard HID (Human Interface Device) reports to 1000 updates per second maximum. Even if you buy an 8000Hz keyboard and set it to 8000Hz in software, plugging it into a USB 2.0 port automatically caps it at 1000Hz.
How to Identify USB 3.0 Ports
Color coding (most motherboards):
- USB 3.0: Blue plastic inside the port
- USB 3.1: Red or teal plastic
- USB 2.0: Black or white plastic
Symbol identification: Look for “SS” (SuperSpeed) printed next to the port. USB 3.0+ ports include this marking.
Check your motherboard manual: Your motherboard documentation lists exactly which ports support USB 3.0+. Rear motherboard ports almost always perform better than front panel ports, which often route through internal hubs.
Best Practices for High Polling Rates
For 1000Hz keyboards:
- Any USB port works (2.0 or 3.0)
- Prefer rear motherboard ports over front panel
- Avoid USB hubs if possible
For 4000-8000Hz keyboards:
- MUST use USB 3.0 or higher ports
- Use dedicated ports (not shared hubs)
- Update motherboard USB drivers
- Enable XMP/DOCP in BIOS for optimal USB controller performance
Test after connecting: Always run a polling rate test after connecting your keyboard to a new port. Just because a port is labeled USB 3.0 does not guarantee it delivers full performance; driver issues, BIOS settings, or motherboard quality can all limit actual speeds.
FAQs
What is an online keyboard polling rate test?
An online keyboard polling rate test measures how many times per second your keyboard sends data to your computer. A higher rate, like 1000 Hz or 8000 Hz, means faster response and smoother performance. These polling rate tests help gamers and typists see if their device performs at peak speed.

You can open a keyboard polling rate test online tool or app in your browser, press any key repeatedly, and the tool instantly shows your average Hz value. It’s quick, accurate, and doesn’t require any installation, just a stable internet connection and a responsive keyboard.
What’s the difference between 1000 Hz and 8K keyboard polling rate?
A 1000 Hz polling rate means your keyboard updates your computer every 1 ms, while an 8K keyboard polling rate updates it every 0.125 ms. The 8K option offers ultra-smooth input, ideal for competitive gaming where every millisecond counts. However, not all systems or games benefit noticeably from 8K speed.
Is the Keyboard Inspector tool reliable for polling rate checks?
Yes, Keyboard Inspector polling rate tools are popular for quick and reliable testing. They give you real-time feedback on your keyboard’s signal consistency. Many users also compare their results on Reddit or GitHub discussions to see how their device stacks up against others.
Which polling rate is best for gaming keyboards?
For gaming, most players prefer 1000 Hz as the sweet spot between speed and stability. Some high-end models like Gamemax keyboards or other performance-focused brands offer 8000 Hz, but you’ll only notice a difference in ultra-fast reaction games or e-sports environments.
Can I test my keyboard polling rate without downloading software?
Absolutely. There are several keyboard polling rate test online tools that work directly in your browser. These web-based testers are lightweight, safe, and perfect if you don’t want to install extra software. Just open the tool, press a few keys, and see your polling rate instantly.
What is a good polling rate for a keyboard?
A good polling rate is 1000 Hz. It means your keyboard reports data every 1 millisecond. Most gaming keyboards support this rate for faster response.
Is a higher polling rate always better?
Yes, but only up to a point. Increasing from 125 Hz to 1000 Hz improves speed noticeably. Going beyond 1000 Hz gives minimal gains unless you use ultra-high-speed gaming gear.
How can I check my keyboard’s polling rate?
Use an online keyboard Hz test or polling rate checker. Press any key repeatedly, and the tool will display your average Hz value in real time.
What happens if the polling rate is unstable?
An unstable polling rate can cause missed keypresses, double inputs, or inconsistent delays. Try switching USB ports, updating firmware, or using a direct connection instead of a hub.
Why do Bluetooth keyboards have more delay?
Bluetooth sends data wirelessly and compresses signals to save power. This increases wireless latency. Most Bluetooth keyboards operate at 125–250 Hz, which is slower than wired 1000 Hz models.
What’s the difference between polling rate and response time?
Polling rate (Hz): how often your keyboard sends data. Response time (ms): total delay from pressing a key to seeing it on screen. They’re related, but response time also includes processing and display delays.
Why does my keyboard test show a different Hz than my software says?
Browser tests measure polling rate through JavaScript timing, which adds 10-20% overhead compared to direct USB monitoring. If your keyboard is set to 1000Hz but the browser test shows 700-900Hz, this is completely normal. Browser tests are excellent for relative comparisons between keyboards, even if absolute numbers are not laboratory-precise.
What’s the difference between scan rate and polling rate?
Scan rate is how often your keyboard checks its key matrix internally (inside the keyboard). Polling rate is how often the keyboard reports that data to your computer through USB. Both matter. A keyboard with an 8000Hz scan rate but only a 125Hz polling rate will still feel slow because the computer only receives updates every 8ms.
Do I need USB 3.0 for high polling rate keyboards?
For 1000Hz keyboards, no USB 2.0 works fine. For 4000Hz or 8000Hz keyboards, yes USB 3.0 is required. USB 2.0 physically caps at 1000Hz maximum due to bandwidth limitations. Check your motherboard manual to identify which ports support USB 3.0.
How can I optimize Windows for better polling rate performance?
Enable Ultimate Performance power plan, disable USB Selective Suspend, update your USB chipset drivers, and use rear motherboard USB ports instead of front panel ports or hubs. These changes reduce system interference that can artificially lower your keyboard’s effective polling rate.
What polling rate do professional gamers use?
Over 90% of professional esports players use 1000Hz keyboards in Valorant, CS2, Apex Legends, and Fortnite. Very few use 8000Hz despite having unlimited budgets. They prioritize reliability and consistency over theoretical spec advantages.
